number of draft picks

this is a discussion within the Saints Community Forum; anyone know for sure how many picks we have in this year's draft?
according to this guy, we should have 9 (7 rounds, plus 2, minus one)

is that right?
&quot;one plus two plus two plus one...&quot;
extra credit ...

so again, that's a first, a second, a third, 3 fourths-ours, one from kc, one from philly, or, 2 thirds- ours and one from philly, two fourths- ours and one from kc, a fifth, and a sixth......
now, do we get any supplemental ones?
